This Sustainable Asset Valuation (SAVi) report assesses the economic and environmental impact of nature-based infrastructure (NBI) and hybrid infrastructure interventions in the Bogotá River basin, concluding that these investments provided significant net benefits in flood protection and water quality.

This report by the NBI Global Resource Centre evaluates the economic, social, and environmental viability of implementing hybrid infrastructure—combining nature-based and grey infrastructure—to manage urban flood risks in Sekondi-Takoradi, Ghana. The analysis focuses on priority locations including Sekondi Market and Bakado, comparing a hybrid approach against a business-as-usual scenario.

The Nature-Based Infrastructure Global Resource Centre, in collaboration with UNEP and local stakeholders, conducted a cost-benefit analysis of nature-based infrastructure (NBI) and hybrid scenarios across 12,000 hectares in four districts of Ghana to mitigate extreme weather impacts under three climate scenarios (SSP1, SSP3, and SSP5).
